These are dropping, and fast. There is a mountain of them clogging up outpost at 3 keys, and it seemed fairly obvious that this wasn’t the price from the moment I started looking.

My first thought was, ‘oh, I can do a range of 2 – 2.5 keys...’ Then I kept looking, and found something horrible.

I could only find ONE that was sold at that price either. Fearing the worst, I pushed onwards, but my fears were assuaged (at least for a while.) These seem to be going at 2 keys, or equivalent, and to highlight the fact that this has dropped, some are even unsold for 2 keys.

Seems pretty conclusive to me. Would not be surprised if this drops further in the future.

Let me know what you think :D
